EMF = BLv sin θ
- EMF=volts
- L = lenght
- v = velocity
EMF = Δ(BA) / Δt
- A = area
- t = time
- EMF = volts
φ = B A cos θ

φ = magnetic flux
E = E0 sin ω t
- E0 = peak output voltage
- ω = 2*pi*f = angular velocity
E0 = N A B ω
- E0 = peak output voltage
- ω = 2*pi*f = angular velocity
VP / VS =NP / NS
- V = voltage
- N = no. of turns
If NP > NS,

then the transformer is a step-down, which reduces AC voltage.
NP < NS,

then the transformer is a step-up, which increases AC voltage.
VP × IP = VS × IS
- V = voltage
- I = current
